The Orioles confirmed that they had no intention of releasing Willis and they do want him to remain a member of the squad. This is interesting news because the Orioles only have one left hander in the big league bullpen. With a stacked left handed American League East lineup, the Orioles will be looking for left-handed bullpen help as the season progresses.
From what I hear, the Orioles simply wanted to get Willis some innings under his belt before evaluating him enough to get him to the big league squad. However, the initial agreement of being a reliever wasn't mutual apparently as Willis was hoping to impress enough to become a starter once again.
